The company published Grisaia: Phantom Trigger 04 digitally for Switch in September 2020, and released Grisaia: Phantom Trigger 05 digitally for Switch in November 2020. Prototype released the sixth volume (pictured right) of the game for Switch on September 22. The sixth volume launched on PC via Steam in April 2019.

The Grisaia: Phantom Trigger anime adaptation of the game opened in Japan in March 2019, and Frontwing released an English dub. The Campfire crowdfunding campaign for Grisaia: Phantom Trigger the Animation Stargazer, the sequel to the anime, reached its 10 million yen (about US$92,000) goal less than 24 hours after it launched in July 2019, and it opened in theaters in Japan in November 2020. Each episode was originally planned to be 60 minutes long and would adapt one volume of the original visual novel.
Frontwing released the first two volumes of the game with English text for PC via Steam in April 2017 (on the same day Frontwing released the volumes in Japan). The seventh volume launched on PC via Steam in July 2020.
All three of the main games inspired anime and manga adaptations.
Sekai Project launched Frontwing‘s The Fruit of Grisaia on Steam in 2015 after meeting its Kickstarter goal for a Western release of the game trilogy. Frontwing and Sekai Project have also released The Labyrinth of Grisaia and The Eden of Grisaia on Steam. Frontwing released the The Fruit of Grisaia bonus episode “The Leisure of Grisaia” on Steam in May 2016.
Vol.8 will tell the story of a major war in the Grisaia universe. The US-Japanese joint anti-terror organization CIRS and the SORD (Social Ops, Research & Development) agency will team up to invade the headquarters of The Fatal Answer (TFA). The protagonist Haruto, Rena, and other Mihama Academy students trained to become SORD operatives, will also be present at the battlefield.
Grisaia Phantom Trigger is a series of visual novels that tell a new story after the Fruit, Labyrinth, and Eden of Grisaia. Frontwing released the first volume of Phantom Trigger in 2017. Despite the numbering, Vol.8 is technically the ninth volume in the series as the company released Vol.5.5 in the middle.
